Timber sash and slimline glazing across Oxford
Sash windows define much of Oxford’s historic core. Georgian and high-Victorian townhouses in Jericho, North Oxford and Park Town almost universally require timber sash with slim double glazing on any street-facing replacement, and single-glazed replicas may be the only option on college-owned streets. Legacy Windows is a comparison service that puts your job in front of Listed-Building experienced sash specialists across OX1 to OX4.

Frequently asked questions
Will I need Listed Building Consent from Oxford City Council? If your property is listed, always. On unlisted properties inside a conservation area, planning consent is normally needed for any street-facing sash change, and the conservation officer typically requires timber, matching glazing bar profiles and slim double glazing.
Is slimline double glazing thermally effective? Yes. Modern 12–14mm sealed units with warm-edge spacers, low-e coatings and argon fill achieve Uw values of 1.4 to 1.6 W/m²K — Part L compliant in a Listed Building context.
How long does a bespoke timber sash quote take? Survey and joinery order usually take four to eight weeks; installation for a full house of six to twelve sashes typically runs five to twelve days on site.
